I buy my lanterns at the local dollar store called the Dollar Tree. Throughout the year, they will have thematic themes including polka dots. I buy and save because the price is right! The choices vary from store to store. Check your local dollar store because online you have to buy a case.

I have done my room in blue with white polka dots. I have white background bulletin boards with scalloped border. I also used ribbon as a border, twist and turned it for a unique spin. All letters are blue polka dots, I will even make tem by using blue paper and gluing dots to them. I have 14in wooden letters to spell out READ of course painted blue with white dots. Bought plastic containers from dollar tree added white sticky dots. I love my room. Gender friendly. I thought I had more pics but I guess I deleted

I'm a huge fan of Target's Dollar(ish) bins by the entrance. I'm a sucker if it's under $3. I generally like colors and patterns vs a specific theme. I love polka dots and stripes. I find that I can add to this year after year building on what I have. Last year I added a paisley polka dot look to my room.
